Claire Elise Boucher, known as Grimes, was hospitalized on Saturday after guest-starring on Saturday Night Live alongside her husband Elon Musk and Miley Cyrus.

On an Instagram post, Grimes said she had a panic attack and that the experience was “quite scary.” She added that “it’s a good time to start therapy.”

“I’d be crying after every show,” she explained.
